Subject: [PATCH] Fix a (long standing?) bug in ip_output(): if
 ip_insertoptions() is called and ip_output() encounters an error and bails
 (i.e. host unreachable), we will leak an mbuf. This is because the code calls
 m_freem(m0) after jumping to the bad: label at the end of the function, when
 it should be calling m_freem(m). (m0 is the original mbuf list _without_ the
 options mbuf prepended.)
